Can not accomplish to smooth completely；The dynamics provided is low, it is impossible to support heavier workpiece, easy landing.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic pressure tail ejection device, and it can effectively solve the problem that in background technology and exists
Problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of hydraulic pressure tail ejection device, including tailstock set
Cylinder, piston bottom, fixing guide pin bushing, rolling center, spring socket sleeve, thrust roller bearing, Bearing housing, tail top piston rod, stroke are adjusted
Monoblock, tail top cover seat, tail top case shell, tail top cylinder shell, tail top bonnet and sensor block；Described rolling center passes through thrust roller axle
Hold and be connected with tailstock with Bearing housing；Described tailstock is set in fixing guide pin bushing；Described fixing guide pin bushing is set in tail
In top cover seat, and pass sequentially through piston bottom and spring socket sleeve and be connected with tail top piston rod；It is sequentially provided with on the piston rod of described tail top
Tail top cylinder shell, tail top bonnet, Traffic control system block and sensor block；Described tail top cover seat and the fixing connection of tail top case shell；Described tail
Top bonnet is connected by tail top cylinder shell and tail top case shell are fixing.
Further, described Traffic control system block is provided with three.
Compared with prior art, the beneficial effects of the utility model are: this hydraulic pressure tail ejection device simple in construction, maintenance side
Just；Hydraulic system provides power, and mobile more smooth, the thrust of generation is the biggest, it is possible to the workpiece that convenient processing is heavier.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The all other embodiments obtained, broadly fall into the scope of this utility model protection.
Referring to Fig. 1-5, a kind of technical scheme of this utility model offer: a kind of hydraulic pressure tail ejection device, including tailstock
1, piston bottom 2, fixing guide pin bushing 3, rolling center 4, spring socket sleeve 5, thrust roller bearing 6, Bearing housing 7, tail top piston rod 8,

Top 4 are connected with tailstock 1 by thrust roller bearing 6 and Bearing housing 7；Described tailstock 1 is set in fixing guide pin bushing 3
In；Described fixing guide pin bushing 3 is set in tail top cover seat 10, and passes sequentially through piston bottom 2 and spring socket sleeve 5 and tail top piston rod 8
Connect；Tail top cylinder shell 12, tail top bonnet 13, Traffic control system block 9 and sensor block 14 it is sequentially provided with on described tail top piston rod 8；
Described tail top cover seat 10 and the fixing connection of tail top case shell 11；Described tail top bonnet 13 is by tail top cylinder shell 12 and tail top case shell 11
Fixing connection.
Further, described Traffic control system block 9 is provided with three.
It is of the present utility model when design: by tail top case shell 11, this hydraulic pressure tail ejection device is placed in lathe upper hopper chute,
There is provided power by hydraulic system, promote tail top piston rod 8 to seesaw, and then promote rolling center 4 to be moved forward or rearward；
By thrust roller bearing 6, rolling center 4 can rotate so that workpiece can Smooth Rotation, and then carry out rotate processing, by
Then hydraulic control, rolling center 4 can be accurately positioned, and will not rock, it is ensured that machining accuracy；Adjust by stroke is increased or decreased
The quantity of monoblock 9, changes the movement travel of tail top piston rod 8, and then the movement travel of change rolling center 4, expands and use
Scope.
Embodiment the most of the present utility model, for the ordinary skill in the art,
